Aune M2 32BIT/DSD Portable Player Coming Soon
Superb reproduction of the original live event or original recording session
Comfortable for long listening sessions
Versatile with all genres
Your first choice!
ARM+CPLD as the core audio framework
The M2 uses native decoding & asynchronous clock technology from independent R&D. The kernel program took over a year. It’s all about the sound quality.
Five TI chips to constitute the whole power supply system
CPLD technology
The M2 uses high precision clock as the master device, and uses sampling pulse to force synchronizing the WAV data from ARM. ARM uses pingpong buffer to process the data, and it’s guaranteed the I2S data won’t be interfered by operation or the micro SD card reading. Everything is based on high precision clocks, which leads to the extremely high fidelity!
The M2 uses CRISTEK’s crystal oscillator of which the lowest phase noise can be -170dB. It’s extremely low.

The M2 chooses the best clock crystal oscillator, only to pursue the best sound.
Superb hardware design from experience accumulation
The main board is rationally quartered - equally divided into the power supply part, the digital part, the DAC part and the Amp part. The whole circuit uses high level water flowing type wiring; the analog part is mirror-symmetric; every port is in the closest position.
Creative design of built-in Amp positive and negative power supply Class A
The Amp part occupies 1/4 of the PCB, which is quite a lot among all the portable players on the market. It uses the structure of the ultra-low distortion Op Amp and 10 discrete transistors. The output uses NPN+PNP geminate transistors. The quiescent current at last stage of each transistor is 15MA. Ultra linear Class A biasing.

Excellent tuning
To quote from a review of an aune product, “....really shows you the true nature of what’s on your head.” Each of aune products is designed for the reproduction of the true music. It’s more than just a cold machine. And we always follow the rule that the tuning should bring out the natural and musical sounds, present the real texture of each instrument, and be based on our understanding of music
Part of the tracks used for tuning:
1)From the Drottningholm Music
2)Try a little tenderness
3)Allegretto con variazoni
4)Sonate, Finale: Vivo
5)Circo della vita
6)Played twice
7)Winin' boy blues
8)Sweet Georgia Brown
9)Allegro di Molto
10)Concertino for clarinet and string orch; Homage a Mozart
11)House of the rising sun
12)Zigeunerweisen
13)Stompin' at the Savoy
14)Concertino for double bass and string orch; Ballad
15)Erstrand, Lars
16)ornbergs Blue Five, Tomas
Part of the chief tuner’s comments on 2 songs (All Rights Reserved):
Try a Little Tenderness is a piano recording stressing the recording quality and musical taste. The audio engineer is a two-time recording award winner, and he was responsible for both recording and mixing for this song. It was recorded in a jazz bar. If you have been on such occasions, you should know how direct and vivid the recording is. The piano is crystal clear yet solid, as if you could see it. In the meanwhile, the drum brush is also as clear as if it was in the same room with you. The cymbal is soft and open along with the melody. Jazz is a genre that contains a lot of improvisation and grooves. Therefore, the kit that matches it the best should be able to bring out the wood texture of the piano which plays the main melody, and not lose the shininess and fluency of the notes. Moreover, the player’s humming along with the music should also be well represented by the kit, so that the listener can feel the atmosphere and infection of the jazz bar to the most.
House of the Rising Sun is sung by Cyndee Peters, a wellknown female artist in Sweden. She was invited several times to perform for both the Royal Family of Sweden and Pope John Paul II. Nelson Mandela was also one of her fans. House of the Rising Sun, adapted from a late-19th century song of black people, describes the hard life of the poor people in New Orleans. The arrangement uses percussion instruments with good transient, so it’s easy to place them on the sound stage. The sax solo should be found a bit ahead of other instruments. At the beginning of the song, the listener is supposed to hear the bell and cymbal coming out respectively from the left and the right side of the sound stage, with their bright and sleek timbre. The sound must be bright and airy, and not too hard or incisive. Back to Cyndee Peters’ singing, her voice and her method of voice production are very special. The explosive power of her voice along with the percussion instruments builds the rich and deep sound stage, and also expresses the emotions in the song very well, which should be clearly felt during playback.
